There are six kindoms of bacteria. Archaebacteria is unicelluar. They are archaebacteria, Eubacteria, protista, fungi, plantae, and animalia. They are one of first organisms on earth because they can live without oxygen. Eubacteria is very common and they use oxygen to live but they can live without it. They are used in making food and can cause disease. There are three different shapes. Cocci is round, Bacilli is rod shapedm and Spirilla is spiral shaped. When classifying bacteria, if the stain is purple, it is gram stain positive, and pink is gran stain negative. These tell what bacteria it is.
